United States Patent 3,455,767 DOUBLE DECK SINGLE FACER MACHINE HansMeister, Cherry Hill, N.J., assignor to Samuel M. Langston Company,Camden, N.J., a corporation of New Jersey Filed Aug. 17, 1965, Ser. No.480,453 Int. Cl. B32b 31/12, 3/28 US. Cl. 156-470 9 Claims ABSTRACT OFTHE DISCLOSURE that they are interchangeable.

This invention relates to a double deck single facer machine, and moreparticularly to such a machine structurally interrelated in a novelmanner.

In accordance with the present invention, two single facer machineshaving identical frames are disposed at different elevations in astaggered fashion whereby only the front end of the upper machine issupported by the lower machine. A discrete support means is provided tocooperate with the lower machine for supporting the upper machine. Sincethe frames on each of the machines are identical, only one productionline is required for the frames and either machine could be an upper ora lower. The components of each machine are identical and thereforethere is no need for manufacturing or storing components which areusable only on one of the machines. Also, the upper and lower machinesare structurally interrelated in a manner so that the corrugating rollsand other components of the lower machine may be removed withoutinterfering with the upper machine.

The staggered arrangement of the machines has other advantages. Thus,maintenance and observation of components such as doctor rolls, adhesiveflow patterns, clean-out fingers, adjustment of crescent fingers, etc.are capable of being accomplished on either machine as if the othermachine were not present. The individual machines are structurallyinterrelated in a manner whereby a paperboard manufacturer may installonly the lower machine and at some later date, add the upper machinethereto. This event could occur when a manufacturer does not have asufficiently large business so as to justify a double deck arrangement.By adding an upper deck at some later date, the manufacturer has theadvantage that additional floor space is not required.

Quite often, manufacturers move from one location to another, such asduring an expansion program. In the event that such changes do notfacilitate the use of double deck machines and adequate space isavailable, the upper deck may be removed and mounted on a bed platewhereever desired. Thus, it will be noted that maximum versatility isone of the main advantages of the present invention in conjunction withthe other advantages discussed above.

A single motor may be used to drive rotating components of the upper andlower deck. The drive system preferably includes provisions fordeclutching the corrugating and pressure rolls of either machineindependently ice of the other. At the same time, this system mayinclude components for declutching the drive with respect to the gluemechanism independently of each other and independent of the drivingconnection to the corrugating and pressure rolls. The driving system ofthe present invention permits the accomplishment of these features Whilebeing simple, rugged, and inexpensive.

It is an object of the present invention to provide a novel double decksingle facer machine.

It is another object of the present invention to provide a double decksingle facer machine having identical upper and lower modulesstructurally interrelated in a staggered fashion.

It is another object of the present invention to provide a double decksingle facer machine structurally interrelated in a manner to facilitateease of maintenance and observation of components.

It is another object of the present invention to provide a double decksingle facer machine having upper and lower modules each provided withidentical frames so that either one could be an upper or a lower deck.

It is another object of the present invention to provide a double decksingle facer machine comprised of upper and lower decks structurallyinterrelated in a manner whereby the upper deck may be added after thelower deck has been installed and operated.

Other objects will appear hereinafter.

For the purpose of illustrating the invention, there is shown in thedrawings a form which is presently preferred; it being understood,however, that this invention is not limited to the precise arrangementsand instrumentalities shown.

FIGURE 2 is a sectional view taken along the line 22 in FIGURE 1.

FIGURE 3 is a sectional view taken along the line 33 in FIGURE 2.

FIGURE 4 is a slightly enlarged detailed view of the structure withinthe circle designated as A in FIGURE 2.

FIGURE 5 is a transverse sectional view of the lower single facermachine.

Referring to the drawings in detail, wherein like numerals indicate likeelements, there is shown in FIGURE 1 a double deck single facer machinein accordance with the present invention designated generally as 9. Themachine 9 includes a lower single facer machine 10 and an upper singlefacer machine 11. The machines 10 and 11 are identical modules havingidentical frames.

The single facer machines 10 and 11 are each preferably of the typedisclosed in copending application Ser. No. 480,415 entitled SingleFacer Machine and filed on Aug. 17, 1965, and now US. Patent No.3,390,040. The disclosure in said application is incorporated herein byreference. Since the structure of the machines 10 and 11 is identical,only the details of machine 10 will be described in detail hereinafter.

The machine 10 includes a pair of parallel spaced side frames which maybe designated as a right side frame 12 in FIGURE 3 and a left side frame14. The side frames 12 and 14 support the rotating components and aremounted on a bed plate 16. The frames 12 and 14 are connected to the bedplate 16 by front and rear pairs of bolts disposed on the inner surfacesof the frames. The distance between the bolts of each pair is identical.The side frames are preferably solid cast iron and the bed plate 16 ispreferably sound-deadened to eliminate vibration problems.

A first or lower corrugating roll 18 is rotatably supported by the sideframes 12 and 14. A second or upper corrugating roll 20 is rotatablysupported by a pair of lever arms 22 (only one of which is shown). Thearms 22 are mounted on the side frames 12 and 14 for pivotable movementabout the longitudinal axis of stud 24. The arms 22 are each connectedto a rod extending from separate pneumatic motors 28 (only one shown).The motors 28 are adapted to operate in unison to move the ends of theupper corrugating roll 20 toward the lower corrugating roll 18 bypivoting the same about the longitudinal axis of stud 24.

A pressure roll 30 is supported for rotation about its longitudinal axisby the side frames 12 and 14. A conventional means not shown may beprovided for heating the rolls 18, 20 and 30. The pressure roll 30 issupported at its ends by arms 32 (only one of which is shown). The arms32 are mounted for pivotable movement about the longitudinal axis ofstud 34. The arms 32 are each likewise connected to a separate rodextending from a pneumatic motor 38 (only one of which is shown). Themotors 38 are adapted for simultaneous actuation to move the ends of thepressure roll 30 toward the lower corrugating roll 18 by pivoting thearms 32 about the longitudinal axis of stud 34.

The axes of the rolls 18, 20 and 30 lie substantially in a plane whichis inclined with the horizontal. The axes of studs 24 and 34 lie in aplane which is substantially parallel to the last-mentioned plane. Themotors 28 and 38 all lie in a plane inclined with the horizontal andparallel to the last-mentioned planes.

The pneumatic motors 28 and 38 on one side of the machine are mounted ona support member 36. The motors 28 and 38 on the other side of themachine are likewise supported by corresponding support members. Thesupport members 36 are bolted to the side frames 12 and 14 in a mannerwhereby their removal exposes the bearings for the roll 18. In thismanner, access for maintenance or removal of these rolls is readilyfacilitated. It has been found that this construction will enableremoval or replacement of the lower corrugating roll with a period ofseveral hours instead of several days.

The medium 46 to be corrugated passes over a spreader bar 39 adjustablysupported by the side frames 12 and 14. The spreader bar 39 assuressmooth entry of the medium 46 as will be readily understood by thoseskilled in the art. From the spreader bar 39, the medium 46 may passoves one or more idler rollers and beneath a shower designated generallyas 40. The desirability of providing a shower for preheating andconditioning the medium 46 will be readily understood by those skilledin the art. If desired, a slitter knife may be provided between theshower and the spreader bar 39 to trim side edges of the medium 46.

After preconditioning, the web of medium 46 passes over the uppercorrugating roll 20 and into the nip between the corrugating rolls 18and 20 whereby flutes are formed under heat and pressure. The newlyformed flutes are gently stripped from the nip by one-piece crescentfingers 54 at spaced points therealong and guided around the corrugatingroll 18. A liner 48 extends around the preheater roll 42, around idlerroller 44, passes between the nip of rolls 18 and 30, and is adhesivelybonded to the corrugated medium 46 by the heated pressure roll 30 tothereby form single faced board 50 which exits in the direction of arrow52.

Crescent fingers 54 are disposed at spaced points along the corrugatingrolls. The upper corrugating roll 20 is provided with grooves at spacedpoints therealong to facilitate receiving the upper end of the crescentfingers 54, The crescent fingers 54 are adjustably supported by a rigidfinger bar 56 extending between and connected to the side frames 12 ad14. The fingers 54 confine the corrugated medium 46 to the teeth of theroll 18, but permit it to fluff out very slightly while adhesive isapplied to the flute tips by an adhesive applicator roll 62. Tofacilitate such slight flufiing out, the fingers 54 are provided with adepression or notch in the area between rolls 18 and 62.

The adhesive or glue applicator roll 62 is provided with a peripheraladhesive applicating surface interrupted at spaced points therealong bygrooves 64. A metering roll 66 is provided to meter the thickness ofadhesive on the surface of roll 62. As the medium 46 fluffs out into therelief section on the crescent fingers 54, an even film of adhesive isapplied on the flute tips by the outer peripheral surface of roll 62.

Power cylinders 72 (see FIGURE 5) are supported by the frames below thehorizontal plane of the glue pan for retracting the glue mechanism whichincludes the glue pan 68, applicator roll 62 and metering roll 66. Thecylinders 72 may be identical in size with the power cylinders 28 and 38for simplification of maintenance and storage of spare parts. Thecylinders 72 are pneumatic and have a rod 74 extending upwardly forconnection to the glue pan 68.

A bracket 76 is provided at each end of the glue pan 68. The glue pan 68and the rolls 62, 66 are supported by the brackets for pivotablemovement about a horizontal axis corresponding to the longitudinal axisof shaft 78. Shaft 78 is longer than the distance between the sideframes 12 and 14. The side frames 12 and 14 are rigidly interconnectedby a cylindrical brace 80.

Free floating clean-out fingers 82 are provided. Each clean-out finger82 extends into one of the grooves 64 on roll 62. The clean-out fingersmaintain the proper amount of adhesive in the grooves 64. The entiretyof the clean-out fingers lies between vertical planes containing theaxes of the rolls 62 and 66. Back-up structure in the form of a shaft 84may be provided to limit the upward extent of the clean-out fingers 82.Since the clean-out fingers 82 are free-floating, they areself-adjusting with speed changes and mounted for removal from aposition above the glue pan 68 and do not interfere with the adjustmentof dams or partitions within the glue pan.

In order to facilitate adjustment in the gap between the applicator roll62 and the corrugating roll 18, arms 96 are fixedly secured to the endsof shaft 78 on the outer surface of the side frames 12 and 14. A limitstop 98 is provided on each side frame for cooperation with anadjustable screw member 100 which is threadedly coupled to the terminalend of each arm 96.

The frames 12 and 14 terminate at their upper ends in a horizontalsurface 102. Surface 102 is provided with a pair of tapped holes spacedapart by a distance corresponding to the distance between the bolts ofeach pair connecting the frames to the bed plate 16. In this manner,bolts 104 may be utilized to connect the front end 106 of machine 11 tothe surface 102 on the rear end of the machine 10 as shown more clearlyin FIGURE 3. A discrete support means such as posts 108 and 110 areprovided to cooperate with the machine 10 in supporting the upper singlefacer machine 11. The upper end of posts 108 and 110 are provided withapertures spaced apart by a distance corresponding to the distancebetween the bolts of the pair of bolts securing the rear end of machine10 to the bed plate 16. Hence, the same bolts and apertures which couldbe used to bolt the rear end of machine 11 to a bed plate are utilizedto bolt the rear end of machine 11 to the support posts 108 and 110.

The bed plate 16 is provided with apertures adjacent each end thereoffor receiving bolts 112. Bolts 112 secure an extension 114 thereto atground level. Each of the extensions 114 support the lower end of one ofthe posts 108 and 110. The tapped holes in surface 102' at the upper endof machine 11 (see upper lefthand corner of FIGURE 1) are not used andmay befilled with a dummy bolt if desired. Such dummy bolts wouldprevent these tapped holes from becoming filled with dirt or otherimpurities and thereby interfere with the ability of machine 11 beingused at some subsequent time as the lower deck of a double deck machine.

To facilitate access to the front of the machine 11, the lower machinemay be provided with a catwalk platform 116. Platform 116 may beremovably bolted to the support 36 which are spaced apart further thanthe greatest width of paperboard which can :be processed so as not tointerfere with the exit of single faced board. The use of discretesupport means for the rear end of machine 11 of the upper deckfacilitates ease of maintenance and operation of both machines withoutinterfering with either machine. Access to the rear side of machine 11may be had by way of any elevated platform. The machines 10 and 11 arecapable of being operated independently of one another and are adaptedto function as if the other did not exist.

The double deck machine 9 is provided with a single driving system whichprovides for selective or simultaneous operation of the machines 10 and11. The driving sys tem includes a motor 118 mounted on a base 120. Base120 may be separate from or connected to extension 122 of the bed plate16.

The motor 118 is provided with a V-belt pulley 126. Belts 128 extendaround the pulleys 124 and 130 and in engagement with idler pulley 132.

A vertical plate 134 is bolted at its lower end to the extension 122spaced from and parallel to the side frames of the machines 10 and 11.Plate 134 is provided with a horizontal surface 136 at its upper end anda horizontal surface 138 between its upper and lower ends. A shaft 140is supported on surface 136 by hearing 142. The hub 144 of pulley 130 isrotatably supported on shaft 140 and connected to one side of apneumatic selectively operable clutch 146. The rotary motion of hub 144may be selectively transmitted to the shaft 140 by way of clutch 146.Clutch 146 may be conventional.

The end of shaft 140 remote from clutch 146 is rotatably supported byside frame 150 on the machine 11. Side frame 150 on machine 11corresponds to side frame 14 on machine 10 and are disposed one abovethe other, but staggered with respect to each other as shown moreclearly in FIGURE 3. The side frame of machine 11 opposite from sideframe 150 is designated as 152. Side frame 152 corresponds to side frame12 on machine 10.

Shaft 140 is provided with a gear 154 adapted to be coupled to drive thelower corrugating roll on machine 11. The upper corrugating roll onmachine 11 is designated as 156. Due to the position where FIGURE 2 wastaken, the lower corrugating roll 157 on machine 11 does not appear inFIGURE 2. The gear for rotating roll 157 is designated as 159 and is ameshing engagement with gear 154.

A gear 162 surrounds shaft 140 and is fixedly secured to the hub 144.The drive from gear 162 to gear 170 is by means of an intermediate gear164 which can be engaged or disengaged from gear 162. Gear 162 in thearrangement illustrated is in meshing engagement with a gear 164rotatably supported by a plate 166. Plate 166 is rotatably supported byshaft 168 which in turn is journaled in a bearing on the upright plate134. A gear 170 is keyed to shaft 168 and in meshing engagement Withgear 164.

The shaft 168 is connected by a universal joint shaft 172 to glueapplicator roll 158. Gear 176 is connected by an endless chain to a gear178 for driving the metering roll 160 at a slower speed. Roll 158 onmachine 11 corresponds to applicator roll 62 on machine 10. The meteringroll 160 corresponds with the metering roll 66 on machine 10.

In order to provide for rotation of plate 166 and gear 164 which issupported thereby, a handle 186 is connected at one end to the plate166.

The coupling between the drive system and the lower machine 10 isidentical with that described above the connection with machine 11.Thus, it is not deemed necessary to explain the corresponding structureof machine 10 in detail, except to point out that a shaft correspondingto shaft 140 is supported by a bearing on surface 138. The idler pulley132 is adjustably supported on the plate 134 to facilitates adjustmentof the tension of belt 128 by means of bolt 196 and parallel slots 198in plate 134.

With the motor 118 running, and the air clutches en gaged on machines 10and 11, the corrugating roll and glue applicator roll of each machineare rotating. If it is desired to stop rotation of the corrugating roll157 of machine 11, clutch 146 is disengaged. With clutch 146 disengaged,the applicator roll of machine 11 is still rotating. If it is desired tostop the rotation of the glue applicator roll of machine 11, regardlessof whether the corrugating roll 157 is rotating, it is only necessary torotate the handle 186. This will result in gears 162 and 164 being outof mesh.

Regardless of the operative or inoperative disposition of the componentsof machine 11, the rotation of the glue applicator roll 62 andcorrugating roll 18 of machine 10 may be independently controlled byoperation of the corresponding clutch 146 and/or handle 186.

The platform 116 is removable and need not be present when there is noupper deck. The platform 116 facilitates access to the machine 11 whenit is an upper deck machine.

As pointed out above, the distance between the sets of bolts connectingthe lower single facer machine frame to the bed plate 16 corresponds tothe distance between adjacent bolts 104 connecting the front end 106 ofmachine 11 to the rear end of machine 10 at surface 102. Said distancealso corresponds to the distance between the bolts connecting the rearend of machine 11 to the upper end of support posts 108 and 110. Theserelationships facilitate using either machine 10 or 11 as an upper or alower or by themselves without requiring any additional adaptors ormachines thereby lending versatility to the single facer machine 11.

If machine 11 is not present, machine 10 will be operating with asmaller version of plate 134 and a belt shorter than belt 128 and ofsufficient length to couple pulley 124 to pulley 126. When machine 11 issuperimposed on a machine 10, the only change of components involved inthe conversion to the double deck machine of the present invention is toremoved the old belt together with the smaller version of plate 134 andsubstitute belt 128 and plate 124 therefor.
